I need to use Aha to do customer facing release planning. I also need to use Rally and its project parent-child rollup capability to show my dev team's productivity and hit MBOs.
We have a hack solution whereby we export features (and corresponding release) from Aha to Rally; then create a Rally release with its corresponding child releases; then move the features into the Rally-originated releases so we can do the rollup. We then delete the Aha-originated release from Rally. We also delete the record link from Aha.
It would be far less of a pain simply to eschew exporting the release in the first place.
